NT Rainbow S NiTi Rotary Files

NT Rainbow S NiTi Rotary Files are advanced endodontic rotary instruments engineered for precise, safe, and efficient root canal preparation. Manufactured from heat-treated nickel-titanium alloy with surface enhancement, they combine exceptional flexibility with superior cyclic fatigue resistance — making them ideal for curved and complex canal anatomy.

Key Features

• Innovative heat-treated NiTi alloy: Minimises crack propagation for enhanced cyclic fatigue resistance
• Slim S-shaped cross-section: Superior flexibility for navigating curved root canals
• Efficient debris removal: Reduces preparation time significantly
• Inactive tip design: Safe preparation with reduced risk of perforation and zipping
• Variable pitch design: Enhanced mechanical resistance and reduced tip fracture risk
• Shape memory: Retains pre-curved shape at room temperature for easy customisation
• Taper value markings on handle for quick identification
